fall into the grateful dead category of legend. by that i mean there is a large segement of the population that has no idea who they are, or have ever heard a song by them, but they are acknowledeged by their peers as great, have a large (enough) and very dedicated fan base, put in years and will probably quit whenever they say quit and not be forced out.

so we need a grateful dead legends category it can't all be only about registering on the pop culture map.

and no i don't think every underground mc/producer should qualify.
